"netplan apply --debug" vs "netplan --debug apply"

[Michael Vogt]

The output of:
"netplan apply --debug"net and "netplan --debug apply" is very different. One works, one does not but there is no indication that it does not work and the help output is misleading.

 netplan apply --help
usage: /usr/sbin/netplan apply [-h] [--debug] [--sriov-only]
                               [--only-ovs-cleanup] [--state STATE]

Apply current netplan config to running system

optional arguments:
  -h, --help show this help message and exit
  --debug Enable debug messages
  --sriov-only Only apply SR-IOV related configuration and exit
  --only-ovs-cleanup Only clean up old OpenVSwitch interfaces and exit
  --state STATE Directory containing previous YAML configuration

But:
$ sudo netplan apply --debug
[no output]

$ sudo netplan --debug apply
** (generate:56613): DEBUG: 20:16:28.101: Processing input file /etc/netplan/01-network-manager-all.yaml..
** (generate:56613): DEBUG: 20:16:28.101: starting new processing pass

I agree this is confusing and should be fixed! We need to investigate why it is the way it is, I think this is some very old heritage.
